The 3Racing SAK-D651/PU pinion set supplies two M1.2 x 14 x 34mm aluminium pinions, each with 8 teeth, anodised purple for part identification. These pinions are dimensioned for 1/10 scale Sakura D6 Sport installations and are produced to tight tolerances for repeatable gear mesh under race conditions.
These pinions are manufactured with attention to tooth form consistency and concentricity to reduce runout and maintain a stable contact pattern. The reduced rotating mass compared with heavier alternatives aids throttle response, while the aluminium material balances stiffness and serviceability for frequent tuning cycles.
For optimal results, set backlash using a shim or shimless method, verify alignment under a bench test, and recheck after initial track runs. The SAK-D651/PU pinions integrate into established Sakura D6 drivetrains and provide predictable behaviour when changing final drive ratios for different track layouts.
